Abstract
The invention discloses a cylinder body, at the fitting part of the cylinder wall with main bearing, the crack and damage of both can be avoided. The cylinder wall formes an embedded partitioned face at the bearing-shell part, and the cocave mounting partitioned face on the main bearing lid is matched with said embedded partitioned face, and several screw bolts are used to fasten them, so that the effective fit can be obtained.
Description
The invention relates to the invention of cylinder block used on the internal-combustion engine.
Usually, adopt muff joint formula structure on the internal-combustion engine in the employed cylinder block, promptly main bearing cap cooperates with casing wall by parting plane, and fastening with some tight bonnet bolts, to prevent the dislocation of crankshaft hole.
But be not only V-type internal combustion engine; even for straight trans internal-combustion engine; main bearing cap under firing pressure since resiliently deformable both sides to occur asymmetric; this tube-in-tube structure makes casing wall have very big stress at the sharp corner of parting plane, also has, because to-and-fro motion; have and produce the possibility that the casing wall tool breaks and damages; therefore to this V-type internal combustion engine, main bearing cap must be utilized two of each sides, and 4 tight bonnet bolts are fastening altogether, and casing wall is shielded.
The purpose of this invention is to provide a kind of cylinder block, break and the cylinder block that provides is provided for preventing that casing wall and main bearing cap from producing in casing wall and main bearing cap cooperation place.
For achieving the above object, the present invention takes following technological scheme:
A kind of cylinder block is characterized in that:
Casing wall forms embedded assembling parting plane at the bush seat place, and main bearing cap has the assembling parting plane, by in the cooperating of described assembling parting plane and embedded assembling parting plane, and be fastened on the bush seat, on above-mentioned casing wall, form the muff joint structure by some tight bonnet bolts.
The present invention is that casing wall forms embedded parting plane at the bush seat place, and main bearing cap cooperates with embedded assembling parting plane by the assembling of the matrix on it parting plane, and be fastened on the bush seat with some tight bonnet bolts, make and form muff joint formula structure on this casing wall, when main bearing cap resiliently deformable occurs under firing pressure, in this muff joint formula structure, the deformation of main bearing seat does not take place to disturb with casing wall and is broken away from by casing wall.
The good effect of invention:
Can think from foregoing, cylinder block of the present invention is that casing wall forms embedded assembling parting plane at the bush seat place, main bearing cap cooperates with embedded mating face by the matrix parting plane on it, and be fastened on the bush seat with some tight bonnet bolts, just because of the cooperation of this muff joint formula, cylinder block of the present invention, when resiliently deformable takes place in main bearing cap under firing pressure, in above-mentioned muff joint formula structure the distortion of main bearing cap not with wall interference, having prevented that casing wall and main bearing cap from producing breaks and damages, and such result is very effective and practical concerning internal-combustion engine.
Following with reference to accompanying drawing, describe embodiments of the invention in detail:
Fig. 1 is cylinder block of the present invention applied embodiment's on truck V-type 8 cylinder diesels a summary transverse section sectional view.
The following describes specific embodiment about cylinder block of the present invention.With reference to the drawing explanation, Fig. 1 is illustrated in the cylinder block 10 of the applied embodiment of the invention on truck V-type 8 cylinder diesels.This cylinder block 10 is the casing wall (not shown) by the front, the casing wall 11,11,11 of 3 centres, and the casing wall (diagram) of back on fore-and-aft direction by fixed interval be divided into different working areas, between above-mentioned each casing wall, punching respectively about the (not shown) of cylinder chamber, and the piston (not shown) can cooperate the cylinder chamber to reciprocatingly slide, also have, the bent axle (not shown) that is connected with piston by connecting rod is lifted on the casing wall by the main bearing cap of bearing shell (not shown) and front, the main bearing cap 12,12,12 of centre and the main bearing cap of back.Certainly, with the casing wall of the casing wall of the main bearing cap of the main bearing cap of above-mentioned front, middle main bearing cap 12,12,12 and back and front, middle casing wall 11,11,11 and back respectively by 2 bonnet bolts, 18 corresponding being fastenedly connected, formation muff joint structure.
Relevant this muff joint formula structure, below the concrete structure at just middle casing wall 11,11,11 and middle main bearing cap 12,12,12 places describe.In this muff joint formula structure, casing wall 11,11,11 places are formed the embedded assembling parting plane 14 of bush seat 13 earlier by machining, the matrix assembling parting plane 16 at bush seat 15 places on the main bearing cap 12,12,12 is cooperated with embedded assembling parting plane 14, and it is fastened on realization cooperation on the bush seat 13 with 2 tight bonnet bolts 18.That is to say that the simple joint type structure of this cover is gone into casing wall 11,11,11 by setting-in in main bearing cap 12,12,12, can prevent the dislocation of crankshaft hole 17 and bearing shell.
In addition, between the casing wall of front and the main bearing cap of front, same enforcement cooperating of this kind mode between the casing wall of back and the main bearing cap of back.
In diesel engine, firing pressure is passed to bent axle through piston and connecting rod, both sides to occur asymmetric owing to resiliently deformable under firing pressure for the main bearing cap of the main bearing cap of its front, middle main bearing cap 12,12,12 and back, and in the cylinder block 10 of above-mentioned this telescoping structure of applying in a flexible way, the cooperation of muff joint mode makes the wedge angle of parting plane 16 can leave parting plane 14, and cylinder head and main bearing cap are not produced big stress.Even repeatedly motion repeatedly, because the cooperation of this kind mode can prevent also that casing wall and main bearing cap from producing and break and damage.Just because of the disengaging of this kind wedge angle can realize above-mentioned muff joint formula structure, thus even main bearing cap is out of shape, cause that the stress of main bearing cap distortion is not had an effect to casing wall yet under firing pressure, thus casing wall is broken and damage.
Can know from the top embodiment of the invention: the technical scope under the present invention with reference to the drawing explanation, concerning the people that general knowledge is arranged, content sources of the present invention is used inventive concept and can easily objectively come out with other form imbody in its characteristic and essence.Much less, content of the present invention is corresponding with its task, and to the invention success be necessary.
